Activities Task 32

Hydrogen-Based Energy Storage

Operating Agent: Dr. Michael Hirscher

Term: 2013-2018

Third Party Publications:

Applied Physics A: Materials Science & Processing - Hydrogen Based Energy Storage (via SpringerLink)

Purpose and Objectives:

  • Develop reversible or regenerative hydrogen storage materials fulfilling the technical targets for mobile and stationary applications.
  • Develop the fundamental and engineering understanding of hydrogen storage materials and systems that have the capacity to fulfill these targets.
  • Develop materials and systems for hydrogen-based energy storage including hydrogen storage for use in stationary, mobile and portable applications, and electrochemical storage


Hydrogen storage was previously addressed in three IEA HIA Tasks 12, 17 and 22. Task 22, which ended in December 2012, had grown into the largest international co-operation effort on hydrogen ever established. Task 22 mainly focused on mobile applications, but in view of a change to a regenerative energy economy, energy storage in general -- both mobile and stationary -- moved to focus. Based on the knowledge and progress within the field of solid-state H2-storage under Task 12, 17 and 22, the IEA HIA Executive Committee and its experts decided to create Task 32 for further R&D work in the area of hydrogen-based energy storage. Task 32 started 1st January 2013 with duration of 3 years. Sixteen members are participating in Task 32.


Task 32 addresses hydrogen-based energy storage by developing reversible or regenerative hydrogen storage materials. In these materials, the quantitative targets for hydrogen capacities vary significantly depending on the different applications, e.g. the gravimetric density is crucial for mobile applications whereas in stationary systems it plays a minor role. Therefore, for each specific application the targets related to volumetric density, thermodynamics, kinetics, cost and safety are totally different. The fundamental understanding of hydrogen storage mechanisms is the key for a breakthrough in the development of materials with improved properties. The focus is on hydrogen in solid compounds approached by experimental, engineering and modeling (both scientific and engineering) activities. At present, Task 32 consists of 48 R&D projects lead by project leaders from the participating countries. Most involve international collaboration, which is strongly encouraged.

The projects are divided into five working groups:

  • Porous materials (coordination polymer framework compounds, MOFs, ZIFs, COFs, and carbon-based compounds)
  • Magnesium-based hydrogen and energy storage materials
  • Complex and liquid hydrides (borohydrides, alanates, amides/imides-systems, magnesium-based compounds, reactive hydride composites and rechargeable liquid hydrogen carriers)
  • Electrochemical storage of energy (MH-batteries, ion-conduction)
  • Heat storage – concentrated solar thermal using metal hydrides

Participants: Australia, Belgium, Denmark, France, Germany, Greece, Israel, Italy, Japan, Lithuania, Netherlands, Norway, Korea, Sweden, Switzerland, UK, USA
